Abstract: An entrance slit of the spectrometer is illuminated with optical radiation. An optical component images the entrance slit to an optical modulator by the optical radiation and disperses the optical radiation into a spectrum. The spectrum is modulated by the optical modulator The optical component composes spectral non-dispersive measurement radiation of the spectrum and images the entrance slit included in the measurement radiation to an exit slit which may be the same one as the exit slit or a different one. Measurement radiation is detected from the entrance slit with a detector, which converts the measurement radiation into an electrical measurement signal.

Abstract: A method and a measuring system for determining exhaust gas emissions from a moving vehicle by a remote optical measuring technique. The model and/or type of the vehicle under examination is identified, and the driving situation of the vehicle in question is determined at the moment of measurement. A calculatory vehicle model is used to determine a case-specific estimate for the carbon dioxide concentration of the exhaust gas plume depending on the vehicle in question and its driving situation. The accuracy of determining the concentrations of the actual emission gases is improved by eliminating the inaccuracy of the carbon dioxide concentration values.
